Is this ok to give a CF child for a sore throat? It's not a cough suppressant; just has some numbing ingredient in it. It's a comfort thing. I gave my daughter one; she's home with something brewing...She's almost 10 and never had a cough drop so I figure what's it gonna hurt? I know it's a silly question; just curious.....We've already done the honey with tea, salt water gargles extra treatments, all the little tricks...
